If LDAP authentication is enabled, an LDAP authentication bypass vulnerability in Trend Micro Vulnerability Protection 2.0 SP2 could allow an unauthenticated attacker with prior knowledge of the targeted organization to bypass manager authentication. Enabling multi-factor authentication prevents this attack. Installations using manager native authentication or SAML authentication are not impacted by this vulnerability.

An incomplete SSL server certification validation vulnerability in the Trend Micro Security 2019 (v15) consumer family of products could allow an attacker to combine this vulnerability with another attack to trick an affected client into downloading a malicious update instead of the expected one. CWE-494: Update files are not properly verified.

An invalid memory read vulnerability in a Trend Micro Secuity 2020 (v16.0.0.1302 and below) consumer family of products' driver could allow an attacker to manipulate the specific driver to do a system call operation with an invalid address, resulting in a potential system crash.

An untrusted search path remote code execution (RCE) vulnerability in the Trend Micro Secuity 2020 (v16.0.0.1146 and below) consumer family of products could allow an attacker to run arbitrary code on a vulnerable system. As the Trend Micro installer tries to load DLL files from its current directory, an arbitrary DLL could also be loaded with the same privileges as the installer if run as Administrator. User interaction is required to exploit the vulnerbaility in that the target must open a malicious directory or device.

If LDAP authentication is enabled, an LDAP authentication bypass vulnerability in Trend Micro Deep Security 10.x-12.x could allow an unauthenticated attacker with prior knowledge of the targeted organization to bypass manager authentication. Enabling multi-factor authentication prevents this attack. Installations using manager native authentication or SAML authentication are not impacted by this vulnerability.

SteelCentral Aternity Agent 11.0.0.120 on Windows mishandles IPC. It uses an executable running as a high privileged Windows service to perform administrative tasks and collect data from other processes. It distributes functionality among different processes and uses IPC (Inter-Process Communication) primitives to enable the processes to cooperate. Any user in the system is allowed to access the interprocess communication channel AternityAgentAssistantIpc, retrieve a serialized object and call object methods remotely. Among others, the methods allow any user to: (1) Create and/or overwrite arbitrary XML files across the system; (2) Create arbitrary directories across the system; and (3) Load arbitrary plugins (i.e., C# assemblies) from the "%PROGRAMFILES(X86)/Aternity Information Systems/Assistant/plugins” directory and execute code contained in them.

SteelCentral Aternity Agent before 11.0.0.120 on Windows allows Privilege Escalation via a crafted file. It uses an executable running as a high privileged Windows service to perform administrative tasks and collect data from other processes. It distributes functionality among different processes and uses IPC (Inter-Process Communication) primitives to enable the processes to cooperate. The remotely callable methods from remotable objects available through interprocess communication allow loading of arbitrary plugins (i.e., C# assemblies) from the "%PROGRAMFILES(X86)%/Aternity Information Systems/Assistant/plugins” directory, where the name of the plugin is passed as part of an XML-serialized object. However, because the name of the DLL is concatenated with the “.\plugins” string, a directory traversal vulnerability exists in the way plugins are resolved.

IDrive before 6.7.3.19 on Windows installs by default to %PROGRAMFILES(X86)%\IDriveWindows with weak folder permissions granting any user modify permission (i.e., NT AUTHORITY\Authenticated Users:(OI)(CI)(M)) to the contents of the directory and its sub-folders. In addition, the program installs a service called IDriveService that runs as LocalSystem. Thus, any standard user can escalate privileges to NT AUTHORITY\SYSTEM by substituting the service's binary with a malicious one.

Unquoted service path vulnerability on Veyon

On Windows the Veyon Service before version 4.4.2 contains an unquoted service path vulnerability, allowing locally authenticated users with administrative privileges to run malicious executables with LocalSystem privileges. Since Veyon users (both students and teachers) usually don't have administrative privileges, this vulnerability is only dangerous in anyway unsafe setups. The problem has been fixed in version 4.4.2. As a workaround, the exploitation of the vulnerability can be prevented by revoking administrative privileges from all potentially untrustworthy users.

A logic bug in system monitoring driver of Acronis Agent after 12.5.21540 and before 12.5.23094 allowed to bypass Windows memory protection and access sensitive data.

Improper Handling of Insufficient Privileges

Apache HTTP Server versions 2.4.0 to 2.4.46 Unprivileged local users can stop httpd on Windows

Royal TS before 5 has a 0.0.0.0 listener, which makes it easier for attackers to bypass tunnel authentication via a brute-force approach.

TeamViewer Desktop for Windows before 15.8.3 does not properly quote its custom URI handlers. A malicious website could launch TeamViewer with arbitrary parameters, as demonstrated by a teamviewer10: --play URL. An attacker could force a victim to send an NTLM authentication request and either relay the request or capture the hash for offline password cracking. This affects teamviewer10, teamviewer8, teamviewerapi, tvchat1, tvcontrol1, tvfiletransfer1, tvjoinv8, tvpresent1, tvsendfile1, tvsqcustomer1, tvsqsupport1, tvvideocall1, and tvvpn1. The issue is fixed in 8.0.258861, 9.0.258860, 10.0.258873, 11.0.258870, 12.0.258869, 13.2.36220, 14.2.56676, 14.7.48350, and 15.8.3.

An Elevation of Privilege issue was discovered in Aviatrix VPN Client before 2.10.7, because of an incomplete fix for CVE-2020-7224. This affects Linux, macOS, and Windows installations for certain OpenSSL parameters.

A heap information leak/kernel pool address disclosure vulnerability in the AMD Graphics Driver for Windows 10 may lead to KASLR bypass.

An insufficient pointer validation vulnerability in the AMD Graphics Driver for Windows 10 may cause arbitrary code execution in the kernel, leading to escalation of privilege or denial of service.

An insufficient pointer validation vulnerability in the AMD Graphics Driver for Windows 10 may lead to escalation of privilege or denial of service.

An out of bounds write vulnerability in the AMD Graphics Driver for Windows 10 may lead to escalation of privileges or denial of service.

An invalid object pointer free vulnerability in the AMD Graphics Driver for Windows 10 may lead to escalation of privilege or denial of service.

An insufficient input validation in the AMD Graphics Driver for Windows 10 may allow unprivileged users to unload the driver, potentially causing memory corruptions in high privileged processes, which can lead to escalation of privileges or denial of service.
